I'm trying to install Linux Fedora on my late 2012 Mac Mini, but I can only run macOS Catalina (10.15.7). I need a way to write the Fedora ISO to a USB stick. I've had no luck using the Terminal and can't find a suitable app that works on Catalina for this task. Any suggestions would be greatly appreciated!

Consider using an app called Etcher. It's user-friendly and designed specifically for creating bootable USB drives. You can download it from their website and it should work fine on your macOS version.

I had trouble with Etcher too on older versions. Sometimes sticking to the command line works better, especially when dealing with specific OS installs. Just make sure to follow the steps carefully if you're using `dd`!

You can try using the `dd` command in the Terminal, which is similar to how it works on Linux. Thereโ€™s a detailed guide that explains the process and what steps to follow. You'll need to identify the correct device node using the `diskutil` tool, unmount any drives that macOS has automatically mounted, and then apply `dd` with the proper parameters. This method should get the job done!
